Motor generated assist torque control for hybrid vehicles

An electronic control unit for a hybrid vehicle, comprising:

• one or more processors;
• and
• a non-transitory memory storing computer readable and executable instructions which, when executed by the processors, cause the electronic control unit to
• receive an input from an accelerator pedal position sensor of the hybrid vehicle;
• calculate a target torque based on the input;
• determine an engine torque generated by an engine of the hybrid vehicle;
• estimate a motor-generated (MG)-assist torque based on difference between the target torque and the engine torque;
• prevent the motor generator from generating the estimated MG-assist torque during a transmission shifting of the hybrid vehicle;
• and
• send to a motor generator of the hybrid vehicle a signal for generating the estimated MG-assist torque.

A method for compensating a delay of an engine response in a hybrid vehicle, comprising:

• receiving an input from an accelerator pedal position sensor of the hybrid vehicle;
• calculating a target torque based on the input;
• determining an engine torque generated by an engine of the hybrid vehicle;
• estimating a motor-generated (MG)-assist torque based on difference between the target torque and the engine torque;
• preventing the motor generator from generating the estimated MG-assist torque during a transmission shifting of the hybrid vehicle;
• and
• sending to a motor generator of the hybrid vehicle a signal for generating the estimated MG-assist torque.
